Specialty

Nephrology

Specialized diagnosis and treatment of kidney disease, with a unique advantage: integration with gastroenterology to investigate the GI-Kidney interface and manage digestive causes of kidney disease progression.

NU.V.E.M’s nephrology service offers early diagnosis and follow-up of kidney disease with an important clinical advantage: integration with gastroenterology in the same space, allowing investigation of digestive causes often overlooked in the progression of kidney disease.

The gut-kidney connection is scientifically established. Conditions such as enteric hyperoxaluria, intestinal dysbiosis and abnormal oxalate absorption have a direct impact on kidney health; at NU.V.E.M we investigate this interface thoroughly.

When to seek Nephrology

You may benefit from this specialty if you experience one or more of the symptoms below:

Swelling in the feet, ankles or eyelids
Foamy urine or abnormal urine color
Decreased urine volume or frequency
Lower back pain or pressure
Hard-to-control high blood pressure
Recurrent kidney stones
Recurrent urinary tract infections
Digestive symptoms in patients with known kidney disease

What we treat in Nephrology

Chronic Kidney Disease (CKD)

Specialized clinical follow-up with evidence-based strategies to slow CKD progression, preserve kidney function and improve long-term quality of life.

Recurrent Kidney Stones

Complete metabolic investigation of recurrent kidney stones, including assessment of enteric hyperoxaluria, an under-investigated cause related to abnormal intestinal oxalate absorption.

GI-Kidney Interface

Investigation of the relationship between intestinal dysbiosis, enteric hyperoxaluria, leaky gut syndrome and kidney disease progression: a unique integrative approach available at NU.V.E.M.

Recurrent Urinary Tract Infections

Management of recurrent UTIs with investigation of predisposing factors, microbiological profile and targeted treatment to reduce recurrence.

Renovascular Hypertension

Evaluation and follow-up of kidney-related hypertension, with complementary investigation and integrated management with the internal medicine team.

Prevention and Screening

Preventive kidney evaluation in at-risk patients (diabetics, hypertensive patients, family history), with complementary exams and personalized dietary guidance for kidney protection.

Why NU.V.E.M

What sets us apart in Nephrology

  • Nephrology and gastroenterology in the same space, for those who need both evaluations
  • Investigation of enteric hyperoxaluria and dysbiosis as causes of recurrent kidney stones
  • GI-Kidney interface approach: the impact of the microbiota on kidney health
  • Complete multidisciplinary support with no need for multiple referrals
  • ISO 9001 certification: traceability of every exam and treatment decision

For referring physicians

NU.V.E.M offers nephrology evaluation with a diagnostic edge: integration with gastroenterology allows investigation of intestinal causes of CKD progression, recurrent stones from enteric hyperoxaluria, and the impact of intestinal dysbiosis on kidney health — an approach that nephrology alone often doesn’t cover.

  • Complete metabolic investigation in cases of recurrent kidney stones
  • Joint GI-Kidney evaluation with breath tests and intestinal permeability analysis
  • CKD follow-up focused on slowing progression and quality of life
  • Reports and integrated communication with the gastroenterology team
  • Accepts referrals from general practitioners, cardiologists and endocrinologists

Frequently asked questions

What sets NU.V.E.M’s nephrology apart?+

Integration with gastroenterology in the same space, allowing investigation of digestive causes of kidney disease, such as enteric hyperoxaluria and intestinal dysbiosis.

When should I see a nephrologist?+

In cases of swelling in the feet or eyelids, foamy urine, hard-to-control hypertension, recurrent kidney stones or recurrent urinary tract infections.

Is recurrent kidney stones related to the gut?+

Yes. In some cases, altered intestinal absorption of oxalate (enteric hyperoxaluria) directly contributes to recurrent kidney stone formation.

Do you follow patients with chronic kidney disease?+

Yes, with evidence-based strategies to slow disease progression, preserve kidney function and improve long-term quality of life.
